Do you know what the total yardage is or the rating?  As others have said the low rating will help some, but  I could see where a handicap index from primarily playing at a very short course may not travel well.  In other words, you may not get enough strokes at harder courses that you play.

 

The course has to be 1500 yards long (9 holes) at a minimum or 3000 yards for 18 to allow posting for a USGA handicap.  Anything shorter, and you would be limited to a "short course" handicap which are designated with a "SL".  This handicap would only be applicable at the short course where it was established.
 

 

 

According to an earlier post, the course has an official rating of 65.8/113 - so appears to be a legitimately rated course, not a short course.

 

I am curious as well about the total yardage though...

2,830 yards from the regulation tees that i played from, 3,030 from the championship tees

I think we're getting Jlanm and Tin Man mixed up, or at least I am.  a1_smile.gif

 

Jlanm, I'm assuming those are 9 hole yardages.  Seems like a reasonable rating.

 

Tin Man, when you said you were hitting 7 irons on every hole, I wasn't sure if that meant from the tee or your second shot.  You probably meant your second shot.

 

I think I'm just confusing everyone.............

Oh, you're right, I was thinking they were the same poster.  I thought the "7 irons on every hole" comment was with respect to the course we already knew had the 65.8 rating for 18 holes. So I assumed those were second shots, not tee shots - since you knew it was *not* the same poster, you were right to wonder whether they were second shots or tee shots.

 

Good news is I don't think the confusion changes any of our answers... As you say, for Jlanm the rating is reasonable, and for Tin Min the yardages are reasonable.

well..the math is making some sense to me, i understand how you arrived at the 22..now..to play better and lower it!

 

Thank you guys very much for your insight and help.

post #42 of 64

It now makes sense. a1_smile.gif

 

I will go for an SL handicap. 

 

The course down the street has some guys who have out aged their long games, but are deadly when short. The competition is there. 

 

(I have completed the "out aged" part and am working on dangerous......deadly is my goal.)

 

Thanks Everybody!

If you signed up for the SCGA, then you can post your scores there. I am willing to bet the course would be listed and you can post 9 holes. After you submit xscores, it will calculate your hcp. I have seen a few of the executinve 9 hole courses listed with the option to post a scores for 9 holes.

 

Which course is it?

 

post #44 of 64

The Lakes at El Segundo, and the Hotel behind Marvel Studios.

 

Ones a knobby hill and the other a gully. I'm sure the Lakes are eligible. I have my doubts about the Hotel.

 

PS: The 7 iron bit is for those who only want to carry 3 clubs.

Strange I just went to see if i could pick The Lakes on the SCGA site to enter a score and couldn't find it. There is a manual entry option and it should still work.

Thanks for looking. It's a small muni.

I'm having trouble with the handicap, as I mostly play 9 holes, in fact only played 18 holes once so far this year.

 

My scores this year are as follows:

 

101 - 70.1/121

45 - 34.5 / 122

43 - 34.5 / 122

49 - 34.5 / 122

 

Originally I just put in 18 in golfshot, but tried to use their automated handicap system, and ended up with like a 36.4 or something, does that seem accurate??

 

How does the math work? Where does the differential come from?

 

What would be the most accurate way to assess a handicap given mostly 9 hole scores?

Plenty of answers out there (even in this thread) so...

 

Combine nine hole scores.

 

(Score - Course Rating) * 113/Slope * 0.96. There's your differential. Average the best 10 of the last 20 and that's your handicap index.

This should help get you started.  As noted the differential is:  the score you shot minus the course rating.  Take that number and multiply by 113.  Take that result and divide by the course slope.  Round to the nearest  10th.  .5 round higher

 

101-70.1 = 30.9 
30.9*113 = 3491.7
3491.7/121 = 28.85
Differential is 28.9

 

When you combine 9 hole scores you add the course ratings together but not the slope.  The slopes get averaged.

For your first two 9 hole scores:


45+43 = 98
The rating would be 69.0/122

98-69.0 =29
29*113 =3277
3277/122 = 26.86
Differential is 26.9

 

Once you get 20 differentials take  the 10 lowest.  Compute the average of these 10.  Take that number and multiply by .96  This result does not get rounded  up.  Just drop any numbers after the 10th.  That's your handicap index.

 

To find out what your handicap is for a particular course take your  handicap index and multiply it by the slope of the tees you're playing and then divide the result by 113.  Round to the nearest whole number, .5 rounded higher.

 

Until  your reach 20 differentials you can start computing a handicap index with just 5 differentials.

 

If you have 5-6 scores  use the 1 lowest differential.
7-8 scores use the lowest 2 differentials
9-10 scores use the lowest 3 differentials
11-12 scores use the lowest 4 differentials
13-14..........................lowest 5
15-16..........................lowest 6
17...............................lowest 7
18................................lowest 8
19................................lowest 9
20...............................lowest 10


Once you have more than 20 scores, use the most recent 20 to get your lowest 10 differentials


If you want to know how what a "R" index is and how to compute it.......that's going to have to wait. a1_smile.gif

I'm reviving an old one here, but I've got a little twist and I didn't want to start a new thread on the same topic.

 

Yesterday, I showed up at 630am without a tee time.  Normally they have no trouble squeezing in a single, and I planned on playing two rounds.  

 

They put me off the back and said when I come around the front they'll squeeze me in.  I shot a 46 and finished around 830.  Due to a tournament that started at about that time, they couldn't squeeze me on right away, but after a long wait I got back out there. I played the full 18, shooting a 40 on the front, and a 47 on the back.  Because of the delay, I didn't play holes 28-36.  So, do I post an 86 and a 47 or 46 and an 87?  

 

The difference seems insignificant, but its my best score at my new home course.  Actually, an 86 on this course would also be either my best or second best round ever, per differential.  

 

Facts favoring 86/47: I planned to play 36.  Throughout the first 9 hole round, I expected to follow it immediately with the other 9 holes.  I walk, and my feet were killing me on the last 9 (walked 36 the day before)--fatigue definitely set in more than usual so the first 18 holes i played are closer to normal fatigue levels.

 

Facts favoring 87/46:  The 18 consecutive holes, front then back, are logically connected.  The break between the rounds (about 2hrs) separates them further.

Post them as three separate nine-hole rounds. Or not. One stroke either way isn't going to make much of a difference.
post #52 of 64
But then I don't have a course record.

I'll take that as neither is incorrect and post my course record 86. a3_biggrin.gif

Going out to play 27 hole round today (last of the season I'm guessing) which is perfect because I have a 9 hole round that's waiting for a dance partner, I keep an unofficial handicap and the site I use doesn't compute 9 hole rounds.

 

I want to decide ahead of time which 9 holes I will use to complete the left over round so I don't get tempted to cherry pick to create the best round.

 

Can't decide which is better:

 

a) use the first 9 to complete the left-over and treat the following 18 holes as an independent round

b) play the first 18 as a whole round and use the final 9 to complete my left over

 

I'm thinking there are some score impacting factors such as not being in the groove at the beginning and/or fatigue at the end. I suppose it doesn't make a ton of difference, just wondering what other people do and if there is a protocol?

Heading out soon, unless someone chimes in with a compelling reason to do otherwise, I'll be combining my first 9 with the left over and treating the next 18 holes as an independent round. Wish me luck!
